Low computational complexity variable block size (VBS) partitioning for motion estimation using the Walsh Hadamard transform (WHT) [PDF]

, 2009
Variable Block Size (VBS) based motion estimation has been adapted in state of the art video coding, such as H.264/AVC, VC-1. However, a low complexity H.264/AVC encoder cannot take advantage of VBS due to its power consumption requirements.
